FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises bearing frame, combustion chamber with cylindrical part and nozzle secured on bearing frame by suspension assembly to swing in two planes and driven by drives attached to force ring made on combustion chamber. gas generator and turbopump unit including turbine, oxidiser and fuel pump, extra fuel pump and gas line communicating turbine outlet with combustion chamber head via suspension assembly. Note here that fuel pump comprises two independent stages with independent interconnected shafts coupled with extra fuel pump by device designed to transfer torque and vary rpm. Said device is arranged in housing with feed and discharge channels. Note also that turbine shafts and those of fuel pumps of both stages are arranged concentrically to make annular chamber feed channel there between while discharge channel is communicated with pump inlet. Note that said device designed to transfer torque and vary rpm is made up of magnetic gearing comprising discs with permanent magnets arranged in circle with constant pitch.
EFFECT: higher reliability.
